The results of this work present an overall synthesis of several explorations that have been carried out on the enzymatic kinetics of aqueous extracts of amylases of microbial origin as alternatives to plants. These are therefore a few species of actinomycetes, which were isolated and purified from forest soils in the Hassi Mameche and Abd-El-Malek Ramdan area (Mostaganem province from Algeria). ). Then, a screening of the hydrolytic activities of the isolates by morphological, physiological and biochemical tests was established, in order to select the best performing strains. This exploration presents a good initiation for a future exploitation of actinomycete amylases as sources of thermostable proteins, yield and catalytic activity significant.
